Rail-joint.



LOUIS 1VI. DILGER, 0F CANTON, OHIO.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Application filed October 9, 1911. Serial No. 653,648.

To all whom it may concern:

Be it known that I, LOUIS M. DILGER, citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and use ful Improvements in Rail-Joints, of whichthe following is a specification.

This invention has for its primary object a durable and eflicientconstruction of rail joint whereby a practically continuous treadsurface will be produced in the rails, and whereby the rails will besecurely held together and properly supported at the joints, the partsbeing few in number and of simple construction and capable of beingapplied to and detached from the rails.

With these and other objects in view the invention consists in certainconstruction and arrangements of parts as I will hereinafter fullydescribe and claim.

F or a full understanding of the invention, reference is to be had tothe following description and accompanying drawings, in which:

Figure 1 is a perspective view of my improved rail joint looking at theouter side of the rails. Fig. 2 is a transverse sectional View, thesection being taken substantially on the line 2-2 of Fig. 1. Fig. 3 is aperspective view looking at. the inner side of the rails and Fig. 4 is adetail perspective view of one of the angle bars.

In carrying out my invention the ball or tread surface of the rails iscut away or re cessed on the outer side of the joint, as indicated at 1,the ends of the recess terminating back from the oint on both sidesthereof any desired distance. This cut away portion or recess 1 isfilled in by the rounded upper edge 2 of an angle bar 3, said angle barextending along the outer side of the rails, any desired distance beyondboth ends of the recess 1 and fitting against the web and base flange ofthe rails, as best illustrated in Fig. 1. 'On the inner side of therails is an angle bar 4 corresponding substantially in shape andpreferably in size to the bar 3 except that the angle bar 4: is devoidof the rounded upper edge 2, the angle bar 4 having its upper edgeterminating close up underneath the balls of the rails, as shown.

The two angle bars 3 and 4 are recessed in their base flanges asindicated at 5, each angle bar being formed with two recesses, as shown,the recess of one angle bar being in transverse alinement with thecorrespond ing recess of the other angle bar. Chairs 6, two in number inthe present instance extend transversely underneath the rails onopposite sides of the joint and extend upwardly on the outer sides ofthe angle bars 3 and 4: and are received in the recesses 5 and theregistering recesses 7 that are formed in the base flanges of the rails.On the inner sides of the rails, the clamping arms 8 of the chairs 6abut firmly against the angle bar 4 and preferably extend snugly upunderneath the ball or head of the rails, while, on the outer side ofthe rails the clamping arms 8 are initially spaced somewhat from theadjoining angle bar 5 and wedges 9 two in number are driven in betweenthe last named clamping arms and the web portion of the angle bar 3.These wedges are driven inwardly from the outer or non opposing sides ofthe chair and are formed on their outer faces at the adjoining oropposing ends with notches 10 in which the relatively free ends of aspring detent 11 are designed to snap so as to hold the wedges securelyin place. In the present embodiment of the invention the spring detent11 is composed of a fiat spring secured intermediate of its ends to abolt 12 that extends transversely through the web portions of the anglebars 3 and 4 and through the interposed portions of the rails, this boltserving not only to hold the spring in place but also constituting anadditional means for holding the parts together.

From the foregoing description in connection with the drawings, it willbe understood that after the angle bars and chair have been assembled,as shown, the wedges 9 will be driven into place, the spring 11 snappinginto the notches 10 and securely holding the wedges from accidentaldisplacement. Whenever it is desired to disconnect the parts for thepurpose of repair or the like, it is only necessary to pry out the endsof the spring 11 from the wedges and to drive the wedges outwardly,whereupon the parts may be readily dis-assembled.

While the accompanying drawing discloses what I believe to be thepreferred embodiment of my invention, yet it is to be understood thatthe invention is not limited thereto, but that various changes may bemade in the construction, arrangements and proportions of the partswithout departing from the scope of the invention as defined in theappended claims.

Having thus described the invention, what is claimed as new is:

1. The combination with the adjoining ends of rails, of angle barsapplied to the opposite sides of the rails at the joint, the baseflanges of the angle bars and rails being formed with recesses, chairsextending transversely underneath the rails and formed with clampingarms extending upwardly through the said recesses on opposite sides ofthe webs of the angle bars, wedges interposed between one set ofclamping arms and the adjoining side of the adjacent angle bar, andmeans engaging said wedges for preventing the accidental withdrawalthereof.

2. The combination with the adjoining ends of rails, of angle barsapplied to the opposite sides of the rails at the joint, the baseflanges of the angle bars and rails being formed with recesses, chairsextending underneath the rails and formed with clamping arms projectingupwardly through said recesses, one pair of arms abutting against theweb portion of one of the angle bars, wedges interposed between theother set of clamping arms and the other angle bar, the wedges beingformed on their outer faces with notches, a bolt passing transverselythrough the angle bars and the interposed portion of the rails, and alocking spring secured on said pawl and adapted to snap into the notchesof the wedges.

3. The combination with the adjoining ends out rails, the same beingrecessed on one side, of angle bars applied to the rails at the oppositesides thereof, one of said angle bars being formed with a rounded upperedge filling the recess of the rails, the base flanges of the angle barsand rails being formed with recesses, chairs extending underneath therails and formed with clamping arms extending up through said recesses,one set of arms engaging one angle bar, wedges interposed between theother set of clamping bars and the adjoining angle bar, the wedges beingformed in their outer faces with notches and a spring secured to thelast named angle bar and adapted to spring into said notches, whereby tohold the wedges in place.

In testimony whereof I atfix my signature in presence of two witnesses.

LOUIS M. DILGER. a 8.
